纯JAVA环境获取APK信息(包名,版本,版本号,大小,权限...),纯JAVA语言编写PC端获取APK信息
纯JAVA环境获取APK信息:包名,版本,版本号,大小,权限...
纯Java环境获取APK信息需要两个包:AXMLPrinter2.jar 跟jdom.jar,用于反编译XML和解析XML的
项目目录
这个类是获取APK信息的
public class ApkUtil {
private static final Namespace NS = Namespace.getNamespace("http://schemas.android.com/apk/res/android");
@SuppressWarnings("unchecked")
public static String getApkInfo(String apkPath){
ApkInfo apkInfo = new ApkInfo();
SAXBuilder builder = new SAXBuilder();
Document document = null;
try{
document = builder.build(getXmlInputStream(apkPath));
}catch (Exception e) {
e.printStackTrace();
}
Element root = document.getRootElement();//跟节点-->manifest
apkInfo.setVersionCode(root.getAttributeValue("versionCode",NS));
apkInfo.setVersionName(root.getAttributeValue("versionName", NS));
apkInfo.setApkPackage(root.getAttributeValue("package", NS));
Element elemUseSdk = root.getChild("uses-sdk");//子节点-->uses-sdk
apkInfo.setMinSdkVersion(elemUseSdk.getAttributeValue("minSdkVersion", NS));
List listPermission = root.getChildren("uses-permission");//子节点是个集合
List permissions = new ArrayList();
for(Object object : listPermission){
String permission = ((Element)object).getAttributeValue("name", NS);
permissions.add(permission);
}
apkInfo.setUses_permission(permissions);
String s = root.getAttributes().toString();
String c[] = s.split(",");
String versionCode = null;
String versionName = null;
String packageName = null;
for(String a: c){
if(a.contains("versionCode")){
versionCode = a.substring(a.indexOf("versionCode=\"")+13, a.lastIndexOf("\""));
}
if(a.contains("versionName")){
versionName = a.substring(a.indexOf("versionName=\"")+13, a.lastIndexOf("\""));
}
if(a.contains("package")){
packageName = a.substring(a.indexOf("package=\"")+9, a.lastIndexOf("\""));
}
}
System.out.println("\n版本号:"+versionCode+"\n版本名:"+versionName+"\n包名:"+packageName);
String str = "\n版本号:"+versionCode+"\n版本名:"+versionName+"\n包名:"+packageName;
// return root.getAttributes().toString();
return str;
}
private static InputStream getXmlInputStream(String apkPath) {
InputStream inputStream = null;
InputStream xmlInputStream = null;
ZipFile zipFile = null;
try {
zipFile = new ZipFile(apkPath);
ZipEntry zipEntry = new ZipEntry("AndroidManifest.xml");
inputStream = zipFile.getInputStream(zipEntry);
AXMLPrinter xmlPrinter = new AXMLPrinter();
xmlPrinter.startPrinf(inputStream);
xmlInputStream = new ByteArrayInputStream(xmlPrinter.getBuf().toString().getBytes("UTF-8"));
} catch (IOException e) {
e.printStackTrace();
try {
inputStream.close();
zipFile.close();
} catch (IOException e1) {
e1.printStackTrace();
}
}
return xmlInputStream;
}
}直接上代码,下次再补过讲解.
下面这个是一个界面的主类,主要读取APK位置和大小

}实例测试,这是在金山找的
这里只查了包名,版本,版本号,大小,没有查权限,权限被我屏蔽掉了
List listPermission = root.getChildren("uses-permission");//子节点是个集合
List permissions = new ArrayList();
for(Object object : listPermission){
String permission = ((Element)object).getAttributeValue("name", NS);
permissions.add(permission);
}
apkInfo.setUses_permission(permissions);这一段就是获取权限的代码源码下载
